About 200 fires are actively burning in Canada and have consumed about 19,900 square kilometres of terrain, most of it in the last week. View on euronews

Wildfires scorching several Canadian provinces have driven at least 33,400 people from their homes, with smoke now reaching all the way to Europe.

Plumes of smoke from the wildfires burning in Canada have been blown across the Atlantic Ocean to Europe, with more expected to arrive this week, satellite data shows.

The country's legacy of mining means that toxic metals could be carried along plumes of smoke, endangering people in its path.

The white mist seen in France is not dangerous as most of the toxic gases dissipate while crossing the Atlantic ocean. The smoke also tends to remain at high altitude (around 9,000m), therefore having no significant impact on surface air quality.

Smoke from the deadly Canada wildfires is blanketing parts of the US and Europe, causing widespread air quality concerns. The Environmental Protection Agency has reported "very unhealthy" air quality in the Midwest, Northeast, and Great Lakes regions of the US, prompting expert recommendations for precautionary measures.

Wind pushed smoke from Alberta and B.C.’s wildfires to Calgary Tuesday night into Wednesday morning, leading to an air quality warning for the city and a large portion of the province. Some of those fires have grown significantly due to the merging of four smaller blazes into two larger ones.
